Bummer the poll only let me vote for one. I got 2 trucks.
2015 Silverado 3500 DRW crew that's bone stock but has a AAM finned rear diff cover, double deep Mag Hytec trans pan and an AmsOil remote dual oil filter bypass system.
My other truck is a 99 Ram 2500 Cummins that's anything but stock. Full billet competition transmission, stock bore size block and pistons, balanced and blue printed rotating assembly, full modified girdle and studded bottom end, ported and fireringed head, thermal coated pistons, valves and head, studded top end, 188/220 camshaft, ceramic coated compound twin turbos, etc... it's right up around 1000hp. Truck is still in "restoration".
So I voted GM 3500 DRW..
